Microsoft

Microsoft made a $6.2 billion accounting adjustment this quarter that threw it into negative territory for the first time as a public company, the AP reports.

Microsoft took the charge mostly based on the acquisition of aQuantive, an online advertising company Microsoft acquired in 2007.

As MSNBC reports, the "charge was an acknowledgement that the company's struggling online services division — which lost about half a billion dollars in the previous quarter — is a significant financial drag on the company." Microsoft, remember, is the owner of the search engine Bing.
